Fiber Optic Contacts

FOHC

Jewel Ferrule Alignment System

Cannon's

patented*

optical

contacts

allow

the

use of all standard fibers via the field-proven

jewel ferrule alignment system in a size 16 pin

or

socket

contact.

The

jewel

ferrule

system

provides

precise

alignment

regardless

of

fiber

size,

accommodates

fiber

tolerances,

elim-

inates the requirement for a minimum end gap,

and alloys for spring loading of contacts.

Since

the

advent

of

fiber

optics,

fibers

have

been terminated in optical contacts using mes-

sy two-part liquid expoxy. This process is cum-

bersome

and

not

conducive

to

high

volume

prodution.

Optical

contacts

are

now

available

with

solid

state

epoxy.

The

fiber

is

inserted

into

the

contact and the epoxy is reflowed in a cure

fixture.

No

mixing

of

liquids

is

required;

the

volume and flow viscosity is controlled, result-

ing in a perfect bond and the elimination of

clean-up.
